When you use the FILENAME EMAIL Access Method with the EMAILAUTHPROTOCOL=LOGIN option, SAS follows a specific order to determine which credentials to use when authenticating to the SMTP server.

Sending E-Mail through SMTP documents the order of what credentials are used.

Default Credential Order — SAS 9.4M9 (TS1M9) and Earlier

1. ID= (and PW=) in the EMAILHOST= system option
   If specified, SAS uses this user ID for SMTP authentication.
   
   
2. FROM= in the FILENAME statement
   If you do not provide ID=, SAS uses the user ID from the FROM= option.
   
   
3. EMAILID= system option (and EMAILPW=)
   If FROM= does not specify a user ID, SAS uses EMAILID=.
   
   
4. Operating system user ID
   If you do not provide any of the above, SAS uses the OS account running the SAS session. 

Credential Order After Applying the Hot Fix:

1. ID= (and PW=) in the EMAILHOST= system option
   If specified, SAS uses this user ID for SMTP authentication.
   
   
2. EMAILID= system option (and EMAILPW=)
   If FROM= does not specify a user ID, SAS uses EMAILID=.
   
   
3. FROM= in the FILENAME statement
   If you do not provide ID=, SAS uses the user ID from the FROM= option.
   
   
4. Operating system user ID
   If you do not provide any of the above, SAS uses the OS account running the SAS session.
